DHD's Billet Chromoly 30 Spline Spool is a major upgrade for pullers and racers using axles with stock (30) spline counts. For years our spools have been the trusted choice of countless Pro Street, Pro Stock, 2.5, 2.6, 3.0 pullers and drag racers with AAM 11.5 axles. Each spool is crafted from solid 4140 material and manufactured right here in the USA.
Does not have provision for Dodge Reluctor Wheel. Will not work on trucks requiring rear axle speed input.
